Nathaniel Shead <nshead at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nshead at gcc dot gnu.org --- Comment #1 from Nathaniel Shead <nshead at gcc dot gnu.org> --- I haven't been able to reproduce this; it looks like some of the C++ standard library headers were compiled as importable modules (hence the preprocessed file including translated 'import' declarations), but apart from <format> and <string> I'm not sure which other headers have been compiled as such and in which order. (It's worth noting that only mod_impl.cpp is relevant here, mod.cxx would not be used in causing the ICE.)
